I have bought these from poundland. I had to buy a second set as the first set smelt like they had been dipped in car oil! second set were fine & although quite noisy, keep stuff from sticking together & that awful static buildup you get.

You mean for 2 or 3 years I have been using them and not managed to notice the damage?
They will damage in a wash but not in a dryer? Why?
The laundry balls are in place of detergent, which I still use.

Let me explain..... a washer dryer goes from wash to dry without intervention from this mere mortal. To put the balls in the dry cycle would mean sitting in front of the thing waiting for the wash to stop, difficult at 2 in the morning and when I'm at work don't you think. I'll stick to my tried and tested method.

I not sure whether to believe they making all that much difference in the dryer,maybe i am convincing myself its quicker. Also stuff comes out a lot softer , its like putting them tumble dryer cloths in.

But then I did buy them at the Ideal Home Show a few years ago for £10. I use mine all the time, can't really say if they make any difference at all, probably not when I think about it! Me and mum used to have a tradition of buying a really useless thing at the Ideal Home Show each year. The following year we got the electric food bag sealers (don't ask!).

I bought some of these from poundland - they do seem to cut down on drying time and leave clothes less creased. Can't comment on damage point as most of my decent clothes can't be tumble dried anyway so it's only bedding/towels/socks that get put in the dryer usually!
